Not off-topic at all.

Those are the best methods available.  They aren't particularly
cumbersome, and once you get used to them they're fairly trivial.
I even use VPNs to run Smokeping over private wireless links, so
if somebody does crack the wireless encryption all they've found
is the encrypted VPN behind it.

You can use the security features of Apache (for example denying
access to the Smokeping CGI to all but a small range of IPs) but
it's never going to be as secure as the encrypted methods you've
already identified.
